Success With Seeds Lupinus

Lupinus Germination Information

Lupinus Seed Germination How to Sow Lupinus:
  • Before sowing, soak seeds for 24 hours in warm water or nick/clip the hard seed coats
  • Indoors, sow at alternating temperatures of 55 and 70°
  • Expect the annual to germinate in 15-20 days; the perennial in 20-25 days
  • Outdoors, sow the annual in summer for fall germination (where it will overwinter, flower in the spring, then reseed itself), the perennial in spring, and both directly where plants are to grow
  • The perennial Russell Hybrids will flower in 4 months from seed
  • If sowing seed outdoors, we recommend a maximum planting depth of 4X the width of the seed

How to Grow Lupinus:
Transplanting: Transplant when there are at least two sets of true leaves

Spacing: Space 18-24 inches apart in sun to light shade in a well-drained, slightly acidic soil

Temperature: The plants prefer cool summers and high humidity; in warm climates mulch to keep roots cool

Additional Care:  Plant out carefully, as Lupines have long tap roots that resent being disturbed

Appearance and Use:

Producers of abundant, dense spikes of pea-like flowers for use in borders, beddings, and for cut flowers. Lupinus subcarnosus, Texas Blue Bonnet, is a 1 foot tall annual that in spring or early summer sports blue flowers with a white or yellow spot. At the same time of year, the perennial (Zones 4 to 7) Russell Hybrids sport impressive 1-3 foot tall flower spikes of yellow, purple, red, orange, white, pink, or blue. Leaves of both are dark green and palmately compound
